Casa Batlló Magic Nights is a series of evening events that take place on the roof terrace of Casa Batlló, a UNESCO World Heritage Site and one of the most famous buildings designed by Catalan architect Antoni Gaudí. During the summer season, the stunning dragon-back terrace of Casa Batlló is transformed into an intimate concert venue, hosting a variety of musical performances, ranging from jazz and flamenco to classical and modern pop.
